The modern city of Alamo, where "Winter Texans" come to enjoy the "Land of Two Summers," is far different from what Peter Ebenezer Blalock and George T. Hawkins from Mississippi envisioned as a great cattle ranch when they purchased 32,000 acres of Spanish land grants on the north side of the Rio Grande. In 1909, the land was sold to John T. Beamer and his backers, who envisioned a sugarcane empire; they formed the Alamo Land and Sugar Company. The sugar market collapse led to colonization, bringing trainloads of prospective buyers to Alamo who would mainly farm and open businesses. The Alamo townsite was incorporated in 1924 and celebrates its 100-year anniversary in 2024. In that time of development, the community witnessed steady economic growth. Its history includes raids by Mexican bandits, a taxi driver helping catch a bank robber, a mayor and a former police chief duking it out, the tragedy of a train/truck crash killing 34 farmworkers, damage from Hurricane Beulah, and gaining one of the largest flea markets in Texas.
